Discover commerce shops and route product searches across them; orders are placed against the chosen shop's adapter.","canonicalUrl":"https://shop.fast.xyz","transport":"stdio","install":{"npm":"npx -y @fastxyz/mcp@latest","bundle":"https://shop.fast.xyz/fast-mcp.mcpb"},"capabilities":["search","list-merchants"],"checkoutStates":{"nonTerminal":["submitted","pending","processing","in_progress","submission_unknown"],"terminal":["placed","failed","cancelled"],"success":"placed","guidance":"These states apply only to the checkout submission / order-placement confirmation step, not the ongoing merchant order lifecycle. Only `placed` means the adapter confirmed order placement, and it is terminal only for checkout submission; later fulfillment statuses such as `shipped` or `delivered` are separate. Non-terminal states mean checkout is still processing; `failed` or `cancelled` mean placement did not complete or was cancelled. Report `refund_status` separately when present.","selfCheckout":"For self-checkout handoff, Fast returns a hosted checkout link and does not track the resulting merchant order lifecycle after the handoff."}}
